Definitions

  • the field of the disclosure relates generally to caps for fluid dispensers, and more specifically to self-sealing caps for chemical dispensers.
  • Some known fluid storage dispensers include a flexible body that may discharge a liquid contained therein through an opening in the dispenser when a squeezing pressure, for example from an operator's hand is applied.
  • Some known dispensers may include a sealing means that provides a subsequent sealing action after the pressure is removed, but such dispensers require a two-handed arrangement with these dispensers wherein the closing action must be done by the operator's second hand.
  • Some other known dispensers simply require that each hand manipulate one of two parts to facilitate closing the fluid dispenser.
  • a known housing for a control valve used on a squeeze type fluid dispensing container includes a first check valve fixedly coupled inside a housing. When the first check valve is opened, fluid flow is permitted through an opening and out of a tube in the housing. A second such check valve is fixedly coupled inside the first check valve, and when opened, facilitates channeling the fluid flow from the tube into the housing, then through an opening in the housing and back into the dispenser.
  • Some other known fluid dispensers provide a dual-valve system. Such dual valve assemblies respond to differences in pressure, and cooperate to dispense the fluid from the dispenser, or seal the openings thereof during non-use.
  • the cap may include a valve positioned within the dispenser outlet which is cleaned of material at the end of the dispensing period by the action of the dispenser mechanism herein.
  • dual valve assemblies are not directly exposed to the atmosphere, and fail to allow ambient air into the dispenser to normalize the squeezable dispenser, while maintaining the liquid, and any gaseous product associated with the liquid, within the dispenser during periods of non-use.
  • a fluid dispenser in one aspect, includes a dispenser made from a flexible material and having a body portion and a cylindrical mouth portion extending from the body portion, the mouth portion defining an opening further defining a lip extending about the opening, a cap operable to engage the mouth portion of the dispenser, the cap comprising an aperture therethrough operable to dispense a fluid stored within the dispenser, and a cylindrical insert sized for placement within the opening between the mouth portion and the cap.
  • the cylindrical insert includes a substantially solid plug having a first axial hole therethrough and a second axial hole therethrough, a first reed valve operably attached to the plug to close the first axial hole from an outside of the dispenser, and a second reed valve operably attached to the plug to close the second axial hole from an inside of the dispenser.
  • an insert sized for placement within an opening of a dispenser includes a substantially solid plug having a first surface, a second surface, and first and second axial holes extending from the first surface to the second surface, a first reed valve operably attached to the first surface of the plug to close the first axial hole, and a second reed valve operably attached to the second surface of the plug to close the second axial hole.
  • a method dispensing a fluid from a flexible dispenser includes applying a positive pressure to the dispenser to force the fluid through a first axial hole formed in a plug placed in a opening of the dispenser, the pressure causing a first reed valve mounted on a side of the plug opposite the fluid storage to move away from the first axial hole to allow the fluid to pass through, the positive pressure further causing a second reed valve on a side of the plug where the fluid is contained to maintain placement to substantially seal a second axial hole formed in the plug, releasing the positive pressure to allow the first reed valve to return to a position that substantially seals the first axial hole and allows the second reed valve to open thereby allowing air to enter the dispenser through the second axial hole until a difference in pressure between an interior and an exterior of the dispenser is reduced to substantially zero, and allowing the second reed valve to substantially reseal the second axial hole.
  • FIG. 1 is schematic illustration of an exemplary dispenser 10 used for storing an amount of fluid 12 therein.
  • Dispenser 10 includes a body portion 14 for use in containing and storing fluid 12.
  • dispenser 10 is fabricated from a flexible material, such as, but not limited to a polymer or plastic.
  • a mouth portion 16 extends from body portion 14 and includes an orifice 17 that is sized and oriented to enable fluid 12 to be introduced into or out of dispenser 10.
  • Mouth portion 16 includes an outer surface 18 configured to be coupled to a cap 20.
  • Orifice 17 defines a lip 19 at an end of the mouth portion.
  • outer surface 18 includes a plurality of threads 22 that are sized and oriented to threadably couple with a plurality of corresponding threads 24 disposed on cap 20.
  • cap 20 may be coupled to mouth portion 16 over outer surface 18 using any coupling method such as, but not limited to, friction fitting, a tab and groove combination, and/or with any coupling configuration that enables dispenser 10 to function as described herein.
  • cap 20 includes an inner surface 26 and an outer surface 28.
  • Cap 20 includes a substantially cylindrical cross-section that includes a first end 30 and a second end 32.
  • First end 30 of cap 20 includes an opening 34 that is sized and oriented to receive mouth portion 16 therein.
  • Cap 20 includes a substantially flat top portion 40 that extends across second end 32 of cap 20.
  • cap assembly 20 includes a tip 42 rotatable with respect to and extending from flat top portion 40 of cap 20, and includes an aperture 46 therethrough operable to dispense fluid 12 stored within dispenser 10. In one orientation tip 42 is operable for dispensing of fluid 12, and in another orientation (not shown) tip 42 is not operable for dispensing of fluid 12 as is well known. Alternatively, cap 20 may not include tip 42, but may simply include an aperture (not shown) therethrough that is sized and oriented to enable dispensing fluid 12 from dispenser 10 as described in more detail herein.
  • Self sealing dispenser insert 50 is shown disposed between cap 20 and dispenser 10 in Figure 1 .

  • the first reed valve 100 and the second reed valve 110 are fabricated from a steel of about 0.003 inch in thickness.
  • the reed retainer 102 is made from aluminum.
  • first reed valve 100 is operable to deflect away from the plug 52 when a positive pressure is placed on dispenser 10 to allow fluid 12 to pass from dispenser 10, through the first axial hole 60 and on through the aperture 46 of the tip 42.
  • the second reed valve 110 is operable to deflect away from the plug 52 when a negative pressure is placed on the dispenser 10 to allow a fluid (e.g., air) to pass into the dispenser 10, through the aperture 46 of the tip 42 and the second axial hole 62.
